Abstract Background The relationship between obesity and low bone mineral density (BMD) in older adults is still unclear. Most of the previous study did not account the factor of sarcopenia which is the progressive loss of skeletal muscle mass due to aging, and distribution of fat in obesity. Thus, this study was aimed to explore the correlation between appendicular skeletal muscle mass (ASMM), total fat mass (FM), and truncal fat mass (TrFM) as well as indexes (ASMM/FM and ASMM/TrFM ratio) with BMD in older adults.Methods This was an analytic cross-sectional study. Dual x-ray absorptiometry (DXA) and bioelectric impedance analysis (BIA) were used to assess BMD and body composition, respectively. Appendicular Skeletal Muscle Mass (ASMM) were used in the analysis to reflect sarcopenia, Fat Mass (FM) and Trunkal Fat Mass (TrFM) were used to reflect general and central obesity, respectively. All data were obtained from medical records of Geriatric Clinic of Hasan Sadikin General Hospital Bandung Indonesia from January 2014 to December 2018. The correlation between body compositions variable with BMD were analyzed using Spearman’s test. We also conducted a comparison analysis of body composition variables between low and normal BMD using Mann-Whitney test. Results A total of 112 subjects were enrolled in the study. ASMM and TrFM were positive (rs=0.517, p<0.001) and negative (rS=-0.22, p=0.02) correlated with BMD, respectively. FM were not correlated with BMD, rS=-0.113 (p=0.234). As indexes, ASMM/FM and ASMM/TrFM had positive correlation with BMD, rS=0.277 (p<0.001), and rS=0.391 (p<0.001), respectively. The ASMM, TrFM, and ASMM/TrFM ratio between normal and low BMD also significantly different (p<0.001), meanwhile FM were not (p=0.204).Conclusion ASMM and TrFM have a positive and negative correlation with BMD, respectively. ASMM/TrFM ratio as new sarcopenia-central obesity index has a positive correlation with BMD.

Background and Aim. Normal weight obese (NWO) syndrome is characterized by normal body mass index (BMI), but high amount of fat mass and reduced lean mass. We evaluated allelic frequency of the G/A −308 TNF-αpolymorphism and prevalence of sarcopenia in NWO.Methods. We enrolled 120 Italian healthy women, distinguished into 3 groups: normal weight (NW); NWO, and preobese-obese (PreOB/OB) and evaluated anthropometric parameters, body composition by dual X-ray absorptiometry, blood tests, and genotyping of G/A −308 TNF-αpolymorphism.Results. We found a positive association between sarcopenic obesity and −308 TNF-αpolymorphism. All obese women were sarcopenic and were no carrier of mutation (G/G). Among all G/G, NWO showed significant differences in lean mass and total body lean mass (TBLean) with respect to NW and PreOB/OB (P<0.001). Regarding appendicular skeletal muscle mass index values, 4.21% of NW were sarcopenic (50% G/G and 50% G/A); the same percentage was observed in NWO subjects (100% G/G). Moreover, 2.10% of PreOB/OB were sarcopenic and all were G/G.Conclusion. Our study suggests that TNF-αpolymorphism contributes to sarcopenic obesity susceptibility, in association with body composition. This is the first study that shows the importance of TNF-αpolymorphism to determine TBLean variation in NWO syndrome.

SUMMARY Although treatment for esophageal motility disorder improves dysphagia and increases body weight, the effect of the treatment on body composition is unclear. This study aimed to assess the change in body composition between before and after treatment, the preoperative predictors of muscle increase, and the association between muscle increase and quality of life. Sixty-one patients (achalasia, n = 55; spastic esophageal disorder n = 6) who underwent per-oral endoscopic myotomy were analyzed in a single-arm prospective observational study. Appendicular skeletal muscle mass was measured with dual X-ray absorptiometry before and 3 months after per-oral endoscopic myotomy. For subgroup analysis, patients with postoperative appendicular skeletal muscle mass increase were defined as the muscle-increase group and the rest as the non-muscle-increase group. Preoperative factors related to the muscle-increase group were clarified via multivariate analysis. Further, the improvement after per-oral endoscopic myotomy in health-related quality-of-life score (Short Form-36) was compared between the muscle-increase and non-muscle-increase groups. Appendicular skeletal muscle mass increased significantly 3 months after per-oral endoscopic myotomy (P = 0.0002). The patients who underwent effective treatment (postoperative Eckardt score < 3) showed a significant improvement in appendicular skeletal muscle mass compared to those who did not (P = 0.04). In the stepwise logistic regression analysis, the preoperative Eckardt score (odds ratio: 1.95, 95% confidence interval 1.30–3.26, P = 0.0005) and preoperative serum prealbumin (odds ratio: 0.83, 95% confidence interval 0.70–0.97, P = 0.02) were identified as independent factors related to postoperative muscle increase. The improvements in the Short Form-36 domains of General Health (P = 0.0007) and Vitality (P = 0.003) were significantly higher in the muscle-increase group. The findings show that effective treatment improved the body composition of patients with esophageal motility disorder and that the Eckardt score and serum prealbumin may aid the prediction of increased appendicular skeletal muscle mass after treatment, resulting in a better quality of life.
